Essential oils are efficient in repelling most types of gnats and other insects. The strong scent deters them from the treated areas.
There are three main types of gnats that bite humans. Biting midges, black flies, and sandflies are the most common gnats that affect humans.
- Biting midges are tiny gnats measuring less than ⅛ inch long. They are most noticeable in swarms because of their small size. Biting midges typically feed after sunset and early mornings before sunrise. They turn a dark red from a soft gray after feeding. They are also known as sand gnats and punkies.
- Black flies are common in the United States, measuring ⅕ to ¼ inches long. Their bodies are thick with short antennae and legs. They are dark black, hence the name. They are found around livestock and the home.
- Sandflies are close to the size of biting midges, but they have long, thin legs and humpbacks. They have large wings and range from gray or brown to golden in color.

2 Risks to Using Essential Oils as Gnat Repellent
While essential oils cause less harm than toxic chemicals used by exterminators, there are still risks to using them to repel gnats. These include toxicity and staining.
1. Toxicity of Essential Oils
While most essential oil sprays are listed as pet and child friendly, this isn’t exclusively true. Some oils (like peppermint) are toxic to both humans and animals. Avoid exposing them to peppermint oils.
Be sure to check each essential oil before using it. Here’s what WebMD has to say about some highly toxic essential oils.
Highly toxic essential oils include camphor, clove, lavender, eucalyptus, thyme, tea tree, and wintergreen oils, the researchers noted. Many essential oils can cause symptoms such as agitation, hallucinations and seizures. Symptoms may also include chemical burns, breathing problems, liver failure and brain swelling, among others.
